10 Claims. (Cl. 155-484) This invention relates to improvements in edge rolls for upholstering.

The main objects of this invention are:

First, to provide an edge roll for upholstering which while elfective in maintaining its cross sectional shape when installed is bendable to conform to the part to which it is applied, as for example, one having reverse or compound curves.

Second, to provide an edge roll for upholstering spring assembliesand other upholstered objects such, for example, as furniture and the like which may be economicaleven when flexed or bent.

Objects relating to details and economiesofthe invention will appear from the description tofollow. The in vention is defined and pointed out in the claims.

A preferred embodiment of the invention is illustrated in the accompanying drawing, in which:

Fig. I is a fragmentary plan viewof an edge roll embodying my invention, shown in reversely bent form to illustrate its flexibility and adaptability.

Fig. 2 is anenlarged fragmentary perspective view with the coremember partially extended to illustrate structural details thereof.

Fig. 3is afragmentary'planviewof the stock'from which the core member of Figs. 1 and 2 is formed.

Fig. 4 is an enlarged fragmentary horizontal section of a portion of the bellows folded core member.

Fig. 5 is a fragmentary perspective view of a modified form or embodiment of my invention.

Fig. 6 is a fragmentary plan view of the core member of Fig. 5 in extended form to illustrate the details thereof particularly in the matter of shape.

The edge roll of my invention illustrated in the accompanying drawing is desirably made in considerable lengths and cut into sections of appropriate length for use.

The edge roll of my invention comprises a core member designated generally by the numeral l. A resilient padding 2 is Wrapped around the core member and a flexible covering 3 desirably of loosely woven fabric such, for example, as burlap is wrapped around the padding. The preferred means for associating and securing these parts in assembled relation will be apparent as the description proceeds.

The core member 1 is desirably formed of a strip of embossed paper stock designated generally as 4-. This strip is conformed to provide a connected series of segments 5 of the same general peripheral shape, the

2 adjacent sections beingfoldably connected at 6. In the embodiment shown in-Figs. 1 to 3 these segments have upwardly curved upper edges 7 and straight bottom edges 8, the connection for the segments being of substantially less length than the verticalwidth of the segments.

The conformed strip, as shown in Fig. 3 is bellows folded upon itself .with the segments disposed vertically and transversely of the core member.

The resilient padding .2 is desirably of felted fibrous material such, for example, as felted jute andis wrapped around the core memberwith its edges 9 projecting from the inner side of the core member in overlapping relation and constituting an attaching flap element.

The covering 3 is wrapped aroundthe padding material with its edges in lapping relation to the attaching flap element. A longitudinal row of stitches 10 is .disposed through the attaching flap comprising theattaching flap element of the padding member and thelapping covering closely adjacent to the body of the roll. There is also an outer row of stitching 11 adjacent the outer edges ofthe attaching fiap parts, the stitching being desirably of the overcast type.

To prevent substantial unfolding or extension of the core member when the edge rollis cut into sections I preferably provide a-longitudinal row of stitches 12 extending through thebody portion of the -roll, that is,

through the covering, the-padding and the core member.

The edgeroll thus formedis flexible or bendable-and may be bent without materially afi'ecting its resiliency.

It may be bentgenerally horizontally as indicated in Pig. 1 and also vertically so that itmay be conformed to fit various articles to be -upholstered. This bendability is alsoof material advantage in that it permits the merchandising of the'edge rollin substantial lengths "ments 13 0f the core member 14 corresponding to the core member 1 are of a generalpear shape and-disposed with the small ends thereof'inwardly. The segments are joined for bellows folding asin the embodiment of Figs. lie 4. In-this embodimentthe reinforcingstrip l5-is disposed at the inner edge of the attachingdlap and embraced and retainedby the covering 3.

A beading or attaching strandlti isdiposed-in a fold "l7 ofthecoveringand securedbythe stitches 18; This beading strand"'and'reinforcing "strip are arranged substantially as shown in the Cook and Hormuth Patent No. 2,615,504 issued October 28, 1952, thus particularly adapting the edge roll for attachment to a spring structure as is illustrated in the aforesaid patent.

I wish to point out that by thus forming the core member edge rolls various cross sectional shapes may be readily produced. Edge rolls embodying my invention may be very rapidly and economically produced and While substantially yieldable and bendable maintain their shape under relatively severe stresses or loads.

The forming of the core as I have illustrated provides very substantial flexibility or bendability while at the same time maintaining cross sectional shape.

I have illustrated and described my invention in a highly practical embodiment thereof. I have not attempted to illustrate or describe other embodiments or adaptations as it is believed that this disclosure will enable those skilled in the art to embody or adapt my invention as may be desired.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

l. A bendable edge roll for use in upholstery comprising an elongated body member including a resilient core member formed of an elongated strip of fibrous stock bellows folded upon itself providing a series of connected segments disposed tranversely of the core member in vertically edgewise side by side relation, the segments having edges conformed generally to the cross section of the core member, a resilient padding around the core member, and a flexible covering wrapped and secured around the padding.

' 2. A bendable edge roll for use in upholstery comprising an elongated body member including a resilient core member formed of an elongated strip of fibrous material bellows folded upon itself providing a series of segments disposed transversely of the core in vertically edgewise side by side relation, a resilient padding of sheet material wrapped around the core member with its edges extended at the inner side thereof and disposed in overlapping relation constituting an attaching flap element, and a fabric covering Wrapped around the padding with its edges in lapping relation to said attaching flap element and secured thereto, there being a longitudinal row of stitches through the covering and the padding element closely adjacent the core member.

3. A bendable edge roll for use in upholstery comprising an elongated body member including a resilient core member formed of an elongated strip of fibrous material bellows folded upon itself providing a series of segments disposed transversely of the core in vertically edgewise side by side relation, the segments being of general pear shape and disposed with their narrower edges inwardly, and a flexible covering secured around the core.

4. An edge roll comprising a resilient core member formed of an elongated strip of embossed fibrous material bellows folded upon itself providing a series of segments disposed vertically edgewise and transversely of the core member and in side by side supporting relation, the segments having approximately straight bottom edges and upwardly curved top edges, the connections for the segments being of substantially less length than the vertical width of the segments, for the core member.
